cement production process using alternative fuel

Reliable energy supplier Part 1 World Cement

Cement manufacturing is particularly energy-intensive. In order to reduce the use of expensive primary fuels like coal and oil, cement plant operators focus increasingly on alternative fuels and raw materials (AFR). The use is generally focused on the fuels. Neither the manufacturing process, the end product, nor the emissions may be affected.

ALTERNATIVE CONTROL TECHNIQUES DOCUMENT— NOx

In cement manufacturing, conditions favorable for formation of nitrogen oxides (NO x ) are reached routinely because of high process temperatures. Essentially all NO x emissions associated with cement manufacturing are generated in cement kilns. In cement kilns, NO x emissions are formed during fuel combustion by two primary mechanisms
